Yes, it seems like most every event in the Heavens is organized by Amaterasu's shinki, but they are also the ones that have to respond to emergencies like the forest incident or security measures like their patrols after the chaos of the moon viewing.

[Fortunately, Zelda is quite content talking about big picture topics like the state of the Heavens and the threats posed against them, regardless of whatever reasons Ginia has for seeking her company this evening. It's probably a bit counter intuitive, given that this day is meant to be for fun and relaxing, but Zelda's not really good at either of those things, so.]

Really, for all that we lump all the old gods together, Amaterasu and those that serve her directly seem to be the only ones actually interested in us and the security of Heaven. Or at least they are the only ones willing to be even a bit transparent about it.

[She has her problems with the way Amaterasu handled the forest situation, of course; just about everyone does. She just doesn't see the point in fighting her about it. There are bigger problems to handle and better hills to die on than that.]

It is little wonder that they might be overworked, catering to us as well as whatever tasks they must have as the Queen of Heaven's shinki.
